Being anxious to arrive at some more definite knowledge respecting these "lowes" or "mounds," on the ninth of Nov., 1876, I visited the locality, and by the aid of Mr. Parkinson, the present tenant of Brockhall, I was enabled to make a far more detailed inspection of the battle-field than on a hurried visit about twenty years previously. Mr. Parkinson pointed out the site of the tumulus removed by Mr. Hubbertsty in 1836. Nothing of it, of course, now remains. He said that it was the only mound of the kind he had ever heard of on the Langho side of the Ribble. He, however, pointed out a curious circular agger, about five or six feet broad and a couple of feet high, which enclosed a level area some sixteen or seventeen yards in diameter. It is evidently an artificial work, but without additional evidence it is impossible to say, with any reasonable degree of probability, by whom it was constructed, or to what use it was originally applied. On the steep promontory called "Brockhole Wood-end," Mr. Parkinson called my attention to curious masses of cemented sand and pebble stones, which some persons regarded as artificial grout, that had originally formed part of the massive masonry of an ancient building, the foundations of which had been undermined by the falling in of the earth in consequence of the erosive action of the flood water of the Ribble at the base of the cliff. This, however, I found, on examination, to be erroneous. The "grout" in question is a geological phenomenon, a kind of conglomerate or breccia, formed by the percolation of rain water, charged with carbonic acid and lime, through the mass of glacial or boulder "till" and its sandy and pebbly contents. The "till" contains limestones brought by ice from both the Ribble and the Hodder valleys. The phenomenon is a common one to geologists, and the "concrete" at "Brockhole Wood-end" is an excellent example of it. On gazing across the river at the larger "lowe" of the six-inch Ordnance map, Mr. Parkinson remarked that it appeared to him to be what is termed by geologists an outlier of the boulder deposits on each side of the valley, and therefore, not an artificial mound. He pointed out that the flood waters of the Ribble, Hodder, and Calder met in the plain, and when the "till" was excavated by a kind of circular motion of the combined waters, which the present appearance of the valley indicates, the land situated in the centre or vortex would the longer resist the abrading action, and eventually, as the passage of the currents became enlarged, remain a surviving outlier of the general mass of glacial deposit. On passing the river in the ferry-boat, and, by the aid of a pickaxe, exposing the material of which this mound is formed, I confessed that I could detect no difference in its character or structure from that of the neighbouring geological deposits. Still, as the mound, if artificial, must have been constructed from the boulder
